Detailed explanation-1: -So, tubular secretion in nephron occurs in PCT and henle’s loop.
Detailed explanation-2: -The distal convoluted tubule also contains intercalated (I) cells, responsible for the secretion of acid. The collecting ducts are composed of I cells and also principal (P) cells, which become permeable to water under the influence of vasopressin.
Detailed explanation-3: -Passing through the DCT, the filtrate enters the collecting ducts. Further reabsorption of water takes place in the collecting ducts. 3. Tubular secretion-Secretion is the final step in the formation of urine.
Detailed explanation-4: -The distal convoluted tubule is the nephron segment that lies immediately downstream of the macula densa. Although short in length, the distal convoluted tubule plays a critical role in sodium, potassium, and divalent cation homeostasis.
